* Please find the correct

PIN-assignment in the operating manual “Fronius IG DatCom”

Basic configuration

To ensure the accurate interchange of data between the modem and datalogger the modem must be initialised once. To do this you should connect a PC or laptop to the datalogger on which the latest version of the

Fronius IG.access software is installed. The menu choice "Settings" Æ "Modem for datalogger" allows you to select and initialise the relevant modem.

To configure the modem on a one-off basis you will require:

RS 232 cable for connecting datalogger - PC (must be made up to length, or a ready-made interface cable* can be used)
